Working theory: Turn your CAS logs up to DEBUG. Set a skewAllowance for googleApps to some value. Watch the logs next when you redeploy and see whether you spot the same error, or you actually see a relevant log entry about the skew allowance setting.

I believe I tested this setup and it worked in 4.1.x. Anyway, whenever I try to login to CAS, I am able to authenticate with my active directory username and password, but then I get an error message that “CAS is unavailable”. The other services that don’t use the Google Apps integration are working just fine. In the tomcat error log I get this message: SEVERE: Servlet.service() for servlet [cas] in context with path [/cas] threw exception [Request processing failed; nested exception is org.springframework.webflow.execution.ActionExecutionException: Exception thrown executing [AnnotatedAction@40cf8796 targetAction = [EvaluateAction@78ceaa17 expression = flowScope.service.getResponse(requestScope.serviceTicketId), resultExpression = requestScope.response], attributes = map[[empty]]] in state 'redirect' of flow 'login' -- action execution attributes were 'map[[empty]]'] with root cause java.lang.NullPointerException at org.jasig.cas.support.saml.authentication.principal.GoogleAccountsServiceResponseBuilder.constructSamlResponse(GoogleAccountsServiceResponseBuilder.java:119) at org.jasig.cas.support.saml.authentication.principal.GoogleAccountsServiceResponseBuilder.build_aroundBody0(GoogleAccountsServiceResponseBuilder.java:62) at org.jasig.cas.support.saml.authentication.principal.GoogleAccountsServiceResponseBuilder$AjcClosure1.run(GoogleAccountsServiceResponseBuilder.java:1) … I assume this process is failing because the attribute map is empty, but I don’t know how to fix this problem. I have attached a copy of my deployerConfigContext file. Also, my Google Apps settings are in the cas.properties file. Any thoughts on why this is occuring?
